Filament Sample Spool

The two sides just twist lock together, no glue or screws needed. Center hole is 35mm in diameter. Should be printable with about 14.2 meters of 1.75mm filament ( less than a standard filament sample from maker box of about 16m) going off of the estimate from my slicer (xyzware pro). Pics above show the remainder of the filament after printing only the spool and the type of filament, though I see no reason why this couldnt be printed with any type of filament. settings I am using of are 0.2m
